Carbohydrate intake during physical exercise improves muscle performance and decreases fatigue. We hypothesized that carbohydrate intake during labor which is a period of significant physical activity can decrease the instrumental vaginal delivery rate.
In a previous study we reported a trend toward a decrease in instrumental vaginal delivery and the mount of carbohydrate intake during labour. However due to some limitations no clear conclusion could be drawn.
The present study is designed to examine the relationship between a high calory oral intake (>44 kCal/hour during labour) and the rate of instrumental delivery.
